Retinal telangiectasis was first described by Reese, in 1956. It is an abnormality of the retinal vessels, with irregular dilation and vessel failure. ELS, 44 years old, male, white, from Rio de Janeiro. His complaining was progressive visual loss in the left eye (OS). Corrected visual acuity (VA) was 20/20 in the right eye (OD) and 20/100 in OS. Fundoscopy in OD was normal, and in OS showed capillaries dilation and hard exsudates (circinate) in macular area. After fluorescein angiogram, we performed intravitreal injection of triamcinolone acetonide (4mg/0.1ml) in OS. One month after injection, VA in OS was 20/40, hard exsudates became more visible and angiogram showed a reduction in dye leakage. Due to better visibility, we were able to perform laser photocoagulation on the affected area. Final best corrected VA was 20/20 in both eyes. Although laser treatment is widely recommended, we chose intravitreal triamcinolone injection initially due to the fact that damaged capillaries were too close to foveal avascular zone. Intravitreal triamcinolone injection can be considered in cases of parafoveal retinal telangiectasis with significant decreased vision and changes near foveal avascular zone. However, long term results are not known yet and need to be confronted with other available treatments.
